sADDLE.

SPECIFICATION forming part of Letters Patent No. 536,403, dated March26, y1895.

Application led March 2, 1 8 94.

.To @ZZ whom it may concern.-

Beit known that I, JOHN C. SPEIRS, a citizen of the United States,residing at Worcester, 1n the county of Worcester and State ofMassachusetts, have invented a new and useful -cation, and illustratedin the accompanying sheet of drawings, in which- Figure 1 is a sideelevation partlyin section of my improved device. Fig. 2 is aperspective view of a part I term the forward spring support. Fig. 3 isa perspective view of a part I term the rear spring support. Fig. 4is asectional View illustrating the clamp for securing the two springsupportstogether. Fig. 5 is a sectional view illustrating the clamp forsecuring the rearspring support to the seat-v post,and Fig. 6 representsa modification of the clamp used between the two spring supports.

The special object of my invention is to provide a simple and efficientmeans for securing saddles in place, which shalladmit of a peculiarrocking adjustment hereinafter described, and which shall be very simpleand easy of manufacture.

Referring tothe drawings, and in detail, S represents the usualleather-seat or saddle, to the inside forward end of which is secured ahook H, and to the rear end of which 'is se-v cured a cantle C, thecantle and saddle being riveted together to hold the rear end of thesaddle or seat in place in the usual manner.

My improved support consists of two springs, each of which is madepreferably of a single piece of spring wire bent as hereinafterdescribed, a peculiar clamp for clamping the two together, and apeculiar clamp for clamping the same in place on the seat-post.

25 represents the forward spring support. This forward spring support ismade of a single piece of wire which is bent so as to have straight arms26--26 and the upper curved `34-34, which unite as at 35. l34-34 and 35of this rear spring support, are

Serial No. 502,089. (No model.)

larms 27-27,'which unit-e as at 28, thus forming a hook or clasp, aroundwhich the hook H ,This wire is bentso as to have the two curved arms30-30, and then is bent around on the curve as at 313l, then around thestraight portions 32-32, the upward extending portions 33-33, then thehorizontal portions The portions preferably iiattened, as shown.

The cantle C has a pocket as C into which fits a bolt 20, which hasthreaded on its lower end a nut 23, under which is placed a washer 24,and by this means, the flattened portions 34-34 and 35 ofthe rear springsupport can be adj ustably secured to the cantle.

The arms 26--26 of theforwardspring support 25 are made so that theywill just fit within the arms 32-32 of the rear spring support, vand apeculiar clamp is used to secure the two spring arms together. vThisclamp consists of a cylindrical bushing or sleeve 37, which is cut in ornotched on its ends as at 323-38. Fitting linto this bushing 37 is thepost 36. This post 36 has aslot 39 cut in the same, into which the arms26-26 and 32-32 are passed when the post is in place in the bushing 37.

The post 36 has an extending boss 40 in which is tapped a screw 4l whichhas a head 42. will be lrigidly clamped together, as the bolt 41 isscrewd up. As the bolt 41 is screwed up, it will push or draw the arms32-32 against the arms 26d-26, and this motion will be limited by thearms 26-26 striking or bearing against the bottoms of the notches 38-38.By this means, an efficient, strong, and simple clamp is provided forclamping the two wire supports together.

The leather S may be adjusted on its two spring supports either byloosening the nut 23 and adjusting the-cantle on the rear springsupport, or by loosening the screw 41, and by adjusting the two springsupports relatively to each other.

By this means, the two spring supports IOO A peculiar clamp is providedto secure the rear spring support to the seat-post L, and thus thesaddle in place. This clamp consists of a sleeve 43 which is bored outso as to nicely fit on the seat-post L, and this clamp 43 has extendingarms 444-44, through which is bored a hole, into which the post 46 canfit. These two arms 44-44 are slightly separated from each other asshown. The post 46 has 1o a slot 45 cut in the same as shown, andthesides of the lugs or projections 44-44 are notched so as to receive thearms 30-30 ofthe rear spring support through the slot 45 ofthe post 46.

Fitting on one end of the post 46 is a cap 48 which extends over thepost as at 48, and which will bear against the arm 30 nearest the same.The post 46 has an` extending screwthreaded shank 47, on which isthreaded a 2o nut 50, which is adapted to bear against the sleeve orcollar 4S. By this means, when the nut 50 is screwed up, the extendingsleeve or collar 49 of the collar 4S will be forced against the arm 30nearest the same, and thissleeve 4S is preferably slightly notched or.grooved 1 so as to nicely bear against the arm 30. Asl the nut 50 isscrewed up, this will draw the` other arm tightly against its lug. 44,and` will thus tightly clamp therearspringsupport 3c in place. Also atthe same time, thetendency will be to draw the two lugs 44-44 of` theclamp 43 together around the seat-postL and thus also to secure theclamp ont-he seat-post,

Thus, this clamp by a single nut, accomplishes both functions ofsecuring the rear spring support in place in the saine, and also,

of securingthe clamp to the seat-post, which` provides a very simpleandeconomical construction.

Of course other forms of clamps can be used to secure the two springsupports together, and one of such other forms is shown in Fig.

6. In this instance, the means for securing the two spring supportstogether consists of a clamp made in two parts 500 and 5l, Whichareadapted to bite on thearms-32-32 and 26-26 of thespring supports, and bymeans of screw 52 and nut 53 clamp the two together.

By means of the peculiar clamping means 5o for securing the rear supportto the seat post, it will be seen that I have provided aroeking ortipping adjustment, depending upon the curvature of the arms 30.Thus,`by loosening the nut 50, the saddle can be pushed forward 5 5 orbackward on the seat-post, and can be` tipped at any desired angle, andthe whole` can then be secured in place simply by turn ing the nut 50.This means forms a very efj Iicient adjusting mechanism for saddles ofthis kind, and, of course, so far as this rocking adjustment isconcerned, other spring supports could be used, the only essential partco-operating with this clamp being the two curved arms 2SC-30.

The details of the invention herein described may be greatly varied by askilled mechanic Without departing from the scope of my invention, asexpressed in the claims.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is

1. In a bicyclesaddle, the combination of a leather seat` a springsupport for said seat constructed of cylindrical wire, a seat-post forsupporting the saddle, and a clamp for securing the spring support tosaid seat-post, said clamp consisting of a split clamp having extendedperforated arms, a slotted bolt or post,

l and an exterior threaded clamping device for tightening saidslottedpost to secure the wires ot? thespring support together andA tosecure L the split clamp to the seat-post, substantially Y as described.

2. In. abicycle saddle, the combination of a g leather seat, asupportfor said: seat consisting of a forward spring support` andarear springisupport, anda clamp for securing said supports together, said clampconsisting of a per- 1forated sleeve, a slotted bolt or. post extendingithrough said sleeveand aclamping device at 1 one end` of the slottedbolt` for forcing the i spring wires against` the perforated sleeve and1forsecurfingthem together, substantially as described.

i 3; In a bicycle saddle, the combination of al 'leather seat, a supportfor saidseat comprising iat forward spring support anda rear springsupport, said supports being formed of cylind-rical springwire, a. clampfor securing the parts of said support together, said clamp comprising aperforated sleeve, a slotted bolt or post extending through said sleeveand adapted` to be actuated by an exterior clamping bolt, and a`clamping device for securing the springsu pporttothe seat-post, saidclamping device comprising a split clamp for engaging the seat-post, anda slotted bolt orpost adapted to be actuated by an exterior clampingdevice for compressing said split clamp andsecuring the same to theseat-post, substantially. as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
